Understanding Grasshoppers’ Behaviour

Understanding Grasshoppers' Behaviour

It is quite important to have a basic understanding of grasshoppers’ behavior to effectively manage their population and control their intrusion from unwanted spaces.

Grasshoppers are insects that are famously known for their jumping ability and are found in various habitats worldwide.

The following are three dominant factors that influence their behavior:

  • Food availability
  • Temperature
  • Light

Grasshoppers are herbivores and feed on plants’ leaves, flowers, and seeds. They are diurnal and stay active throughout the day and are known to get even more active in warmer temperatures.

Did You Know!

Grasshoppers can leap as long as 30 inches in one jump. That’s 20 times their body length. That being compared, we could cover an entire football field in a leap if we could jump that many times our body length.

They use their jumping ability to move around and conveniently escape predators.

They have a complex mating behavior that relies on attracting mates using visual and auditory cues. In some species of grasshoppers, males have colors on their wings, which helps attract females.

There are about 11,000 species of grasshoppers around the world.
